Notes:

Breutelia occurs from mid to high elevations in often open habitats, on soil, humus, logs, and occasionally epiphytic or on rocks. The genus likely contains less than 100 species, primarily from the Southern Hemisphere; 30 or more species in the Neotropics. Breutelia is characterized by the robust habit, strongly plicate leaves, alar cells usually differentiated and short rectangular to quadrate, and subfloral whorls of branches. Dana Griffin has published important studies of this genus (1984a. 1984b, 1988); equally important are the floristic treatments published for Mexico and Central America. Keys are adapted, in part, from Griffin (1988). Alar cells are an important feature to distinguish many of the Breutelia species; care should be used when removing leaves so that the alar cells can be scrutinized.
 
Breutelia probablemente contiene menos de 100 especies, distribuidas principalmente en el hemisferio sur. Aproximadamente 30-35 especies presentes en el Neotrópico. Generalmente la mayoría de las especies crecen en sitios abiertos, sobre suelo, humus, troncos en descomposición y ocasionalmente son epífitas o crecen sobre rocas. Breutelia se caracteriza por su hábito robusto, hojas marcadamente plegadas, células alares generalmente diferenciadas, corto-rectangulares hasta cuadradas y ramas subflorales en espiral. Las células alares son una característica importante para distinguir muchas especies de Breutelia; se debe tener cuidado al remover las hojas para que las células alares puedan ser examinadas.

Plants medium sized to typically large and often robust, forming loose to dense tufts, mostly dark green to golden-yellow or yellowish-brown. Stems erect to ascending, occasionally pendent, irregularly to regularly pinnately branched; in cross-section central strand present; mostly densely tomentose, rhizoids papillose. Leaves erect- or wide-spreading, to squarrose-recurved, narrowly to broadly lanceolate from an ovate or obovate-triangular base, plicate, sulcate with differentiated cells or not sulcate with cells uniform, base spreading or sheathing at insertion, apex short to long acuminate, rarely acute; margins plane to commonly revolute, serrulate to serrate above shoulder, often sharply serrate at apex; costae single, strong below, percurrent to commonly short or long excurrent; upper and median cells narrowly rectangular to linear, papillose by projecting distal angles; inner basal cells rectangular-rounded, often porose; alar region differentiated, cells enlarged, in one or more rows, short rectangular to quadrate, smooth, thick-walled. Dioicous. Perichaetia terminal, subfloral innovation present. Setae elongate, stout, smooth. Capsules inclined to pendulous, urn ovoid to subglobose, smooth to more often furrowed when dry; opercula low conic to convex; peristome double, exostome teeth 16, papillose to papillose-granulose; endostome segments 16, papillose or smooth below, cilia rudimentary or bsent. Calyptrae cucullate, smooth and naked. Spores coarsely papillose or tubeculate.
